Answer:
b. 3x - (5y -7)
Step-by-step explanation:
Let x represent "a number". Let y represent "another number."
The "3 times a number" is represented by 3x.
And "5 times another number less 7" is represented by 5y -7.
The difference between these quantities is the second subtracted from the first:
... 3x - (5y -7) . . . . matches selection b.
Answer:
B is Geometric and its next terms are 81, 243, 729...
See example below to complete other problems.
Step-by-step explanation:
Geometric sequences have a pattern that is exponential. Because of this, they do not have a constant rate of change using addition or subtraction. Instead, they have a constant rate through multiplication and division called a common ratio. Problem B is geometric because as you subtract each y value you get a different value each time. It is not a common difference. But if you divide, you find a common ratio.
Example: 27-9= 18 27/9 = 3
9-3 = 6 9/3 = 3
etc. Common ratio of 3
Step-by-step explanation:
one bag has 82 pieces. you can call each kid k. and solve for k. 2 bags times number of pieces. divided by number of kids. 2(82) =5k. isolate k.
2*(82)/5. 164/5. 32 pieces to each child and there will be 4 pieces of candy left over.
The mean of this dot graph is 3.4
The median of this dot graph is 3
The answer is 81.606
next time u might wanna put it in the calculator
